Wikipedia, a free-content online encyclopedia written and maintained by a community of volunteers known as Wikipedians, began with its first edit on 15 January 2001, two days after the domain was registered.

The free online encyclopedia Wikipedia has been criticized since its creation in 2001. Most of the criticism has been directed toward its content, community of established users, process, and rules. Critics have questioned its factual reliability, the readability and organization of its articles, the lack of methodical fact-checking, and its political bias. Concerns have also been raised about systemic bias along gender, racial, political, corporate, institutional, and national lines. Conflicts of interest arising from corporate campaigns to influence content have also been highlighted. Further concerns include the vandalism and partisanship facilitated by anonymous editing, clique behavior, social stratification between a guardian class and newer users, excessive rule-making, edit warring, and uneven policy application.
